Maybe one day you will be on the receiving end of such despicable attacks on private citizens and only then you might change your mind.

You do not get to dictate what cars people get to buy, nor what kind of insurance they must have. That is not how insurance works, premiums will go up for everyone.

Besides, you tell people to sell their cars, while you acknowledge the big financial hit that would involve; who are they going to sell it to? Whoever buys it will also suffer from the vandalism you encourage.
